hi, my computer for no reason sometimes Shuts itself down and then turns itself back on. Doesn't matter if I'm on the Internet, Writting a letter, or playing a graphic intense game. One minute i'll be on and no Probs, the next it turns itself off and then back on. I'm running: Windows xp Epox 4G4A Series MoBo Pentium 4 2.53 ghz CPU 512mb DDR PC2100 MSI GForce 4 Ti 4400 1 Asus 48x cd-rom drive 1 tdk 32x burner 60 gb western digital hard drive 4 case fans Antec true 480 psu i dont think its a heat issue because it turns off at different temps and also i dont think that its a psu issue because i just replaced my generic psu with a nice antec 480 watt psu. please help with this problem. i constantly lose the work that i'm working on. thanks, -jason

Start,settings,controlpanel,system,advanced tab,under startup and recovery click on the settings tab,under system failure uncheck the box automatically restart.

are you sure that this will work? my computer doesnt really restart. when a comp restarts it shuts down properly. mine just turns off and on.

Jason, My computer does the same exact thing. It is driving me nuts! My comp has similar specs as yours but I use an Athlon XP 2000. Doc, I was looking at that option this morning and thought about turning it off. I will give it a try. Thanks!

Hmm... sorry doc but your method did not work for me :( . Does anyone else have any ideas about how to solve this problem? thanks. -jason

It did not work for me either.

run Regedit and go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl Right-click on the "AutoReboot" DWORD [REG_DWORD] Value in the right hand pane -> select Modify -> change it to read 1 (Auto Reboot enabled) -> click OK -> close the Registry Editor. Restart Windows for the change to take effect. From now on the OS will reboot upon locking up, right after writing to the crash log file (if enabled). To disable it, change the "AutoReboot" value back to 0 (default).
